What Is NetInfo? 27

m If the domain has a child on the same computer, the child’s tag is listed, preceded by the

domain name and a /. In this example, computer01/local indicates that the domain has a

child named computer01 that has the NetInfo tag “local.”

Using Command Line Utilities

Several command line utilities that interact with NetInfo are available through the Terminal

application. To ﬁnd out more about them, view their man pages.

The Importance of Planning

The more information you store in NetInfo, the more control you have over your network,

and the more users you can share the data with, while changing it in only one or very few

locations. But the amount of control you enjoy depends on the effort you put into planning

your NetInfo domains and hierarchies. The next chapter in this document provides

information that should help you plan your NetInfo hierarchies.

Important While NetInfo Manager can be used to change NetInfo data, it is easy to make a

mistake that can disable your computer. For example, a Mac OS X process may expect to ﬁnd

a property with a single value; if the property has multiple values, the process’s response is

unpredictable. Use NetInfo Manager as described in the Mac OS X documentation.

Utility Description

niutil Reads from a NetInfo database and writes to one.

nidomain Creates and destroys NetInfo databases. Tells you which domains are served

nigrep Searches all NetInfo domains for all instances of a string you specify.

niﬁnd Determines whether a particular directory exists. If it does, lists its number and
